From 8c3736ce595bccb6322c44a1f853216e278aa635 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Tue, 20 Jun 2023 15:55:47 +0200 Subject: [PATCH] selftests: forwarding: q_in_vni: Disable IPv6 autogen on bridges In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. This will cause this selftest to fail spuriously. The swp enslavement to the 802.1ad bridge is not allowed, because RIFs are not allowed to be created for 802.1ad bridges, but the address indicates one needs to be created. Fix by disabling automatic IPv6 address generation for the HW-offloaded bridge in this selftest, thus exempting it from mlxsw router attention.
